摘要： The present invention relates to an apparatus and method for generation of elliptically polarized shear waves in an earth medium using two shear wave vibrators (20, 22) engaged with the earth medium in cross-polarized attitude and driven at sweep rates having variable phase displacements by means of control circuitry (32, 36).

摘要： The present invention relates to a method of seismic exploration utilizing vibrationally generated, elliptically polarized shear waves (62) in an earth medium (38) for subsequent detection of one or more dimensions of orthogonal particle motion. A preferred form of shear wave source (40) is of a type which couples a continually rotating longitudinal force into an earth medium thereby to propagate an elliptically polarized shear wave (62) for refraction, reflection or subsurface detection, for various forms of exploration.
摘要翻译： 本发明涉及利用地球介质（38）中振动产生的椭圆偏振剪切波（62）进行地震勘探的方法，用于随后检测正交粒子运动的一个或多个维度。 剪切波源（40）的优选形式是将连续旋转的纵向力耦合到地球介质中，从而传播用于折射，反射或地下检测的椭圆偏振剪切波（62），用于各种形式的探索。
